Clay Roof Tile

4.5/5(Based on 1 heritage site)
DescriptionMiṭṭī kī chata ṭā'ila (Clay Roof Tile), also known as *mritika khaprail* (मृतिका खपरैल) in Sanskrit, are ceramic or terracotta roofing units prevalent across the Indian subcontinent, particularly in Karnataka, Kerala, and Tamil Nadu. These tiles, historically used from pre-colonial periods through the modern era, exhibit a density of 1.8-2.2 g/cm³ and water absorption of 10-20% [2]. Fabricated from locally sourced clay deposits – *gramya khaprail* (ग्राम्य खपरैल) reflecting rural origins – the raw material undergoes shaping and firing at 900-1100°C, imparting flexural strength of 15-30 MPa [2]. Traditional construction methods, often employing tile nippers [1] for precise fitting, are evident in heritage structures. Conservation efforts necessitate understanding the tile's composition and degradation mechanisms, including weathering and biological growth. Regional variations, such as Mangalore tiles, reflect localized clay sources and firing techniques. *Maṇ kūrai ōṭu* (மண் கூரை ஓடு), *Maṭṭi paikappu palaka* (మట్టి పైకప్పు పలక), *Maṇṇina chāvaṇi hen̄cu* (ಮಣ್ಣಿನ ಛಾವಣಿ ಹೆಂಚು), *Maṇ mēlkūra ṭaiil* (മൺ മേൽക്കൂര ടൈൽ), *Māṭira chādēra ṭāli* (মাটির ছাদের টালি) are regional names [3].
